I have windows xp on a box.  Due to an incorrect BIOS setting, I had
to reset the BIOS via the CMOS jumper. When it tried to reboot, it
correctly stated that windows had not shutdown properly. When I chose
Start WIndows Normally the entireprogress bar fills and then it just
hangs. If I choose Safe Mode, it loads files up to giveio.sys and then
hangs. I cant get past it. I can boot into the Recovery console, but I
dont know what to do when im in there. Ive run chkdsk from there and
tried to delete the giveio file, but it reappears, I guess from cahce.
How can I fix this box?

Have a look here:

Either way, the first thing to try is disconnecting all of your
peripherals - I have had many instances where USB devices cause
similar symptoms.  Also, given that this file seems to be something to
do with your parallel port, disconnect anything connected to this.

The file does not seem vital to WindowsXP so I would suggest renaming
it from the recovery console and trying again.  Alternatively, try
step by step boot and do not allow it to run.

If the file is reappearing, I would suggest it might by
spyware/malware and your problems therefore a little more difficult to
solve.

As you can access your hard disc, it may be faster to simply back up
your vital data, reformat and reinstall Windows.

Post back with how you get on or if any of the above doesn't make sense!

Good luck!
